To all whom t may concern Be it known that l, DAVID E. EMANUEL, acitizen of the United States, and resident of Des Moines, in the countyof Polk and State of llowa, have invented a certain new and usefulOpera-Chair, of which the following is a specification.

The object of my invention is to provide I an opera chair of simple,durable and inlcontemplated are attained,

expensive construction.

A further object is to provide an opera chair of the type having a seatadapted to slide rearwardly to-permit persons to pass through the aislewith a minimum of interference and inconvenience.

A further object is to provide an opera chair having a back pivoted nearits upper portion and having a seat mounted with relation to said backand adapted to travel into a slot in the back and also having apartpivotally mounted on the back, both of the parts of said seat beingcapable of pivotal movement with relation to the back when the seat israised.

My invention consists in the construction,

arrangement and combination of the vari device whereby the objects ashereinafter more fully set forth pointed out in my ous parts of theclaims and illustrated in the accompanying drawings, in which:

Figure 1 shows a front elevation of a chair embodying my invention. Fig.2 shows a vertical sectional view of the same taken on the line 2-2 ofFig. 1. Fig. 3 shows an enlarged vertical seetlonal view of the lowerpart oit the back and the rear portion oit the seat, ytaken lon the line3-3 ot Fig. 1. Fig. A' shows a vertical transverse sectional view, takenon the line 4 4 of Fig. 3.

1n the accompanying drawings, l have used the reference numeral 10 toindicate' generally the lower support of a chair which may be of anydesired form, for instance, as that of a pedestahzas shown in mydrawings.

0n the upper portion of the supporting member 10 are suitable tramemembers 11.- My improved chair has the'spaced upwardly extending backmembers 12, and suitable arm rests 13, which may be of any desiredconstruction.

Fivotally mounted between the upper ends or the members 12 is a backmember 14:. rlIhe members 12 are inclined from their lower ends upwardlyand -slightly rear- Mounted upon the frame 11 1s a substan-- tiallyrectangular frame 15 having approxlmately the form of a sheet of metalor the like, with its central portion cut away. At the side of the frame15 are upwardly eX- tending members 16, at the upper ends of which areinwardly extending members 17. At the rear outer corners of the frame 15are upwardly extending ears 18, pivotally connected with the back.Mounted upon the frame 15 is a suitable seat member 19 having in itssides grooves to receive the members 17.

In the forward portion of the frame 11 are rollers 20 on which the frame15 travels. It will be seen that the seat 19 may slide with relation tothe frame 15 and also that the forward end of the frame 15 slides freelyon the rollers 20, and that the rear" ward end of said frame issupported by the back 1A and lswings thereon. ln this connection it maybe mentioned that the rear portion of the seat 19lcomprises a plural ityof transverse members 21 connected by a flexible strip 22. rllhe lowerportion of the back 14. is formed with a slot 23, and the parts are soconstructed and arranged that when the seat 19 is in its forwardposition and is pushed rearwardly, the members 21 will slide upwardlyinto the slot 23. The back 1A comprises a wooden member covered on frontand back b a pair of metal sheets. rlFhe wooden mem er extends to thelower ends of the metal sheets, anda space below the wooden member formsthe slot 23.

1n the practical operation and use ot my improved seat, it will be notedthat the seat member 19 projects forwardly beyond the other partsof theseat. Assuming that the seat is not occupied, the seat member 19,. andthe frame '15 may be tilted upwardly to the position shown by the dottedlines in Fig. 2. en it is desired to occupy the seat, the seat member 19and, trame 15 are -lswung downwardly to the position shown over therollers 20 and the back 14 swings rearwardly on its pivot points. On theforward end of the frame 15 is a downwardly projecting member 24 whichengages one of the frame members l1 when the back 15 has reachedperpendicular position, and lthereupon the seat 15 slides rearwardlywith relation to the frame 15 and the members 20 slide upwardly into theslot 23. When the i the fact that the back may be inclined to' variousangles to suit the convenience of the occupant of the seat.

My improved chair is of comparatively simple construction, and can bemanufactured at a small expense.

It will be understood that the chair will be constructed with curvededges, so that with such an arrangement of the parts, there will be nodanger of tearing the garments of the user.

It will be understood that some may be made in the construction andarrangement of the parts of my improved opera chair without departingfrom its essential features and purposes, and it is my intention tocover by this application any such changes which may be included Withinthe scope of my claims.

My seat member is made partially colchanges lapsible for reducing it tothe narrowest width from front to rear, for accommodating passers-by andat the same time affording suiiicient room for the occupant.
